Brooklyn's new Barclays Center has been a boon to the Long Island Rail Road.

LIRR ridership has surged an average of 334 percent on event nights at Barclays, pushing the transit system's 2012 ridership numbers slightly ahead of the previous year's, according to railroad officials.

LIRR ridership has surged an average of 334 percent on event nights at Barclays, pushing the transit system's 2012 ridership numbers slightly ahead of the previous year's, according to railroad officials.

The 18,000-seat Brooklyn arena is home to the Nets and has hosted events including concerts by Jay-Z.

Before the arena opened in September, LIRR would have averaged 990 arrivals and 430 departures at Atlantic Terminal on a typical Thursday evening, officials said. The station is across the street from the arena.

On Oct. 13, when Barbra Streisand performed at Barclays, ridership to Atlantic Terminal jumped 358 percent -- carrying 4,033 passengers, up from the normal 880, officials said. Eastbound departures were up 995 percent from its normal 400 passengers, with trains carrying 4,378 passengers, according to the LIRR.

The railroad has responded to the surge by adding late-night eastbound trains from Atlantic Terminal on event nights.

The service additions are the first since the Metropolitan Transportation Authority made widespread cuts in 2010, including eliminating all LIRR trains to and from Brooklyn between midnight and 5 a.m.

Mark Epstein, chairman of the LIRR Commuter Council, said he hopes the increased ridership will help stave off future fare increases and convince LIRR officials to offer "fan fares" for major sporting events at Barclays and other arenas.

"It proved the adage, if you build it they will come," Epstein said. "It's also a lesson for developers on Long Island -- when you build something, it has to be accessible to mass transit."

While the new arena has provided a boost to its ridership, the railroad had experienced a steady 13-month increase before Sandy./MTA officials shut down trains, buses and subways in anticipation of the storm in order to prevent damage to the fleet. But the storm destroyed some tracks and equipment, limiting LIRR service into Penn Station until Dec. 10, when a full schedule was restored.
